Is your business required to cater to dietary restrictions (like veganism or gluten-free) for company-sponsored events?
As with many legal questions, the answer is - it depends. With various food-restrictive diets becoming the norm, it's difficult to cater to everyone's personal needs. However, if the meal is company-sponsored, and your employees' restrictions are based on religious choices or medical issues, you could run afoul of employment law by not offering reasonable accommodations. Regardless of the reason for restrictive diets, refusing to accommodate them during a work function may find you with dissatisfied - and hungry - employees.
